'Piranha 3D'

t'll be three-dimensional at home only if you have the proper Blu-ray equipment, but even minus that added depth, you'll pretty much get the intended effect of this update of a cult horror classic. The picture has a remarkably good cast for a movie of this nature, led by Elisabeth Shue as the sheriff in a resort area where residents and vacationers alike become targets of lots of you-know-what.
